helm-dragonfly

A Crossplane configuration that deploys Dragonfly via Helm.

Dragonfly is a modern Redis-compatible in-memory datastore that is multi-threaded, memory-efficient, and designed for modern hardware. It's a drop-in replacement for Redis with up to 25x better performance and 80% lower memory usage.

Why Dragonfly?

• 25x faster than Redis on multi-core machines
• 80% less memory for the same dataset
• Drop-in Redis replacement - works with existing Redis clients
• Multi-threaded - utilizes all CPU cores
• Built-in cluster mode without Redis Cluster complexity
